Native Version

uCrop'n'Edit - Image Cropping and Editing Library for Android

This repository is a fork of uCrop'n'Edit, which is in turn a fork of uCrop. I fixed some bugs, updated the dependencies and gradle, and converted much of the code to Kotlin. Furthermore, I added the option to use an ActivityResultLauncher instead of onActivityResult which is deprecated. In addition, in the changelogs you can see all other features I added.

Features

uCrop'n'Edit extends uCrop by adding the ability to change Brightness, Contrast, Saturation, and Sharpness of images. I updated everything and added a few things. You can see all changes in the changelog.

  • image compression format (e.g. PNG, JPEG), compression
  • image compression quality [0 - 100]. PNG which is lossless, will ignore the quality setting.
  • change Brightness, Contrast, Saturation, and Sharpness of images
  • whether all gestures are enabled simultaneously
  • maximum size for Bitmap that is decoded from source Uri and used within crop view. If you want to override the default behaviour.
  • toggle whether to show crop frame/guidelines
  • setup color/width/count of crop frame/rows/columns
  • choose whether you want rectangle or oval(options.setCircleDimmedLayer(true)) crop area
  • the UI colors (Toolbar, StatusBar, active widget state)
  • and more...

Native vs Non-Native Version

I have split this repository into two separate branches:

  • Native: master, develop
  • Non-Native: master-non-native, develop-non-native

Reason for the Split

The main reason for this split was the need for WebP file format support. While it is possible to implement this in the native version using ImageMagick as an additional layer for file handling (as mentioned here), I currently don't have the time to do so.

If someone has the time and interest to implement this, I would greatly appreciate it. Feel free to submit a pull request!

Key Differences Between the Versions

Usage

  1. Include the library as a local library project in your build.gradle:

    allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

...

dependencies {
        implementation 'com.github.jens-muenker:uCrop-n-Edit:version'
}

  2. Add UCropActivity into your AndroidManifest.xml

    <activity
    android:name="com.yalantis.ucrop.UCropActivity"
    android:screenOrientation="portrait"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>

ActivityResultLauncher

  1. Create an ActivityResultLauncher and handle uCrop result.

    private val activityResultLauncher = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
    if (result.resultCode == Activity.RESULT_OK) {
        val imageUri: Uri = UCrop.getOutput(result.data!!)!!
    }
}

  2. The uCrop configuration is created using the builder pattern.

    UCrop.of(sourceUri, destinationUri)
    .withAspectRatio(16, 9)
    .withMaxResultSize(maxWidth, maxHeight)
    .start(context, activityResultLauncher)

Here you can find possible options.

  • Sample - Android ICS 5.0+ (API 21) ( java >= 17 ; gradle >= 8.5 )

  • libpng: 1.6.43
  • libjpeg: 9f (see more here)
